Python 有没有办法计算单选按钮的累积值

我正在编写一个基于CBT的测试程序，我已经完成了注册和登录阶段以及提问阶段，但我想在测试后点击finale submit按钮计算用户的总分，下面是我目前为止的代码

你的问题格式不好。请修改标准规则：若你们有很多元素，那个么就把它们放在列表中。因此，您可以将其保留在列表中，并使用

val[0]，val[1]

而不是

first

，

second

或

val1，val2

。然后您可以使用

for

-loop来处理列表中的元素。我会将带有答案的问题（和正确答案）保留在列表中，并使用

for

-loop来创建

标签和
单选按钮`和
StringVar
。然后我可以使用
for
-loop（和
zip（）
）将
StringVar
中的值与列表中的正确答案进行比较。若要首先计算分数，您必须具有正确答案的列表或其他结构，以便将用户的答案与正确答案进行比较。您的问题格式不正确。请修改标准规则：若你们有很多元素，那个么就把它们放在列表中。因此，您可以将其保留在列表中，并使用
